Makes sense, best of both worlds, full battens up high with most of the benefits of an FB main and shorter battens low to avoid chafe which occurs on monohulls ( usually ok on multis with apparent wind further forward in decent breeze).It doesn't need to be all-or-nothing. Mixing full and partial battens is common and a nice solution. I have 5 battens, 3 of which are full and 2 partial. Less flogging, less chafe, less hardware but not a completely locked shape. For smaller mains you can get away with allslip slides.
